ABSTRACT:
A bed permits changing of bedclothes without moving the person on it and without substantial burden for either the patient or the care-taker. A left and a right carriage member 5 and 6, wheels 15 to 18 and a shaft 7 constitute a carriage. The carriage supports mats 11 and 12 via balancing members 3 and 4 and shafts 1 and 2 and advances the mats 11 and 12 along rails 31 and 32. The mat 12 is stretched between the rails 31 and 32 by fasteners. The balancing members 3 and 4 are rotatably coupled by a shaft to downward extensions 5a and 6a of the carriage members 5 and 6. The shafts 1 and 2 are rotatably mounted in the balancing members 3 and 4. With advancement of the carriage caused by turning a grip 26, the slides 52 and 54 cause the old mat 12 to be released from the fasteners and wound on the shaft 2, while also causing the new mat 11 to be coupled to the fasteners and stretched between the rails 31 and 32.
